I switched from economy energy on the 4 October 18 with £524 credit on my account. They then took direct debits out on the 15/10/18, which were immediately cancelled. Contacted them on 4/11/18 to be told that my refund had been sent to the finance team and would receive an email 3 days before being credited with monies owed. Still awaiting the email. Started the complaints process on 9/12/18 to be told it was with the finance team and the complaint was closed. Will now complain to the ombudsmen. Don't touch them with a barge pole and if you are unfortunate enough to be with them and have credit on the account cancel your direct debits and run it down before leaving.
